It is mainly composed of a pair of legs 4d provided as above. The traveling lifter 4 has a structure that can be raised and lowered by changing the inclination angle of the pair of legs 4d intersecting in the X-shape.

The support base 4b provided on the upper portion is in the shape of a flat plate, and a support piece 4e for hinge-supporting the hanging beam 5 is provided on the support base 4b.

The wheels 4g travel on the gantry 2 and rails 4a provided on both the left and right sides of the conveyor line 3. The carriage 4c has a flat plate shape, and the carriage 4c is provided with motors 4h for driving wheels 4g. The wheels 4g are rotated by the motor 4h so as to travel on the rails 4a.

A pair of legs 4d provided so as to intersect each other in a so-called X-shape between the upper support base 4b and the lower traveling base 4c are connected by a crossing pin 4i at the center thereof. The legs 4d that intersect in a so-called X-shape have a structure that is inclined in the up-down direction about the intersection pin 4i.

A movable pin 4k and a fixing pin 4j are provided at the lower end of each leg 4d. In this case, when the upper end of the leg 4d intersecting in an X shape is the fixed pin 4j, the lower end is the movable pin 4k, and conversely, when the upper end of the leg 4d is the movable pin 4k, the leg 4d is not moved. The lower end is a fixed pin 4j.

The fixed pin 4j on the upper end side of the leg 4d is rotatably connected to the lower surface of the support base 4b. The movable pin 4k at the upper end of the leg 4d is slidably connected in the horizontal direction along the upper guide 4m provided on the lower surface of the support base 4b.

The inclination of the intersection inclination angle is changed vertically.

That is, when the piston 4q of the fluid pressure cylinder 4p extends, the crossing inclination angle of the pair of legs 4d inclines upward, the traveling lifter 4 rises, and the piston 4q of the fluid pressure cylinder 4p contracts. Then, the crossing inclination angle of the pair of legs 4d is inclined downward, so that the traveling lifter 4 is lowered.

The suspension beam 5 is a portion where an electromagnet 6 provided below the suspension beam 5 attracts and suspends a member a made of a magnetic material such as a model rope. For the suspension beam 5, for example, a main girder 5a having an I-shaped cross section is used. A support receiving piece 5b hinge-supported by a main pin 4f is provided between the two support pieces 4e provided on the support base 4b at the lower part of both ends of the main girder 5a.

Fixed plates 5c are provided below the main girder 5a at predetermined intervals. The stationary plates 5c are provided at positions corresponding to the mounting positions of the electromagnets 6 provided below the suspension beam 5, respectively. Up and down moving plates 5d are provided below the fixed plates 5c provided at the bottom of the main girder 5a. Each vertical moving plate 5d is vertically movably suspended by a fixed plate 5c above it via a pair of suspension bars 5e provided on both sides.

Each suspension rod 5e for suspending the vertical moving plate 5d is provided with a vertical moving plate 5d at a lower portion of the hanging rod 5e which is inserted through a through hole 5f provided vertically through the fixed plate 5c. It is connected. In this embodiment, the hanging rod 5e penetrates the vertical moving plate 5d in the vertical direction, and nuts 5g for fixing the hanging rod 5e to the vertical moving plate 5d are provided at the upper and lower portions of the penetrating rod 5e. The upper and lower moving plates 5d are fixed to the lower side of the suspension rod 5e by the upper and lower nuts 5g.

The suspension rod 5e is adapted to be inserted through the through hole 5f of the fixed plate 5c so as to vertically slide inside the through hole 5f. Further, a collar 5h is provided above each suspension rod 5e, and a spiral spring 5i is attached to the suspension rod 5e between the upper surface of the fixed plate 5c and the collar 5h above the suspension rod 5e. The suspension rod 5e is elastically held by the fixed plate 5c by the spring 5i.

A suspension piece 5j is provided at the bottom of each vertical moving disc 5d that is elastically held by each fixed disc 5c via a suspension rod 5e and a spring 5i. The suspension piece 5j has an electromagnet 6 The upper portion is pin-connected by a suspension pin 5k, and each electromagnet 6 is suspended by each up-and-down moving platen 5d via this suspension piece 5j.

The electromagnet 6 has a function of directly adsorbing and transporting the member a from a magnetic material such as a rope by its magnetic force in an energized state, and separating the adsorbed member a when electricity does not flow, By utilizing such a function, the member a is adsorbed from a predetermined position from the magnetic material, conveyed, and lowered to another predetermined position. Each electromagnet 6 is suspended vertically below the main girder 5a via a vertical moving plate 5d and a fixed plate 5c.

A landing confirmation limit switch 7 is provided downward on the lower surface of each fixed board 5c. The landing confirmation limit switch 7 hits the upper and lower moving plates 5d provided below the fixed plate 5c, whereby the limit switch is "ON" and "OFF".

In the landing confirmation limit switch 7, the traveling lifter 4 is lowered, and accordingly the hanging beam 5 is also lowered, and the electromagnet 6 is landed on the conveyor line 3 or the pedestal 2 below the hanging beam 5. It is a switch for confirming that it is installed on the frame 2 or the member a on the conveyor line 3.

A member adsorption confirmation sensor 8 is provided on each vertical moving plate 5d that suspends the electromagnet 6. The member adsorption confirmation sensor 8 is a sensor for confirming whether or not the electromagnet 6 has adsorbed the member a.

Next, the operation based on the configuration of the above embodiment will be described below. When the member-on-frame sorting lifter 1 is driven, the member-on-frame sorting lifter 1 automatically travels toward the predetermined position on the rail 4a based on the instruction information input in advance. The traveling on the rail 4a is achieved by the rotation of the wheels 4g driven by the motor 4h.

For example, when a member a provided at a predetermined sorting position on the gantry 2 is placed on the conveyor line 3, the upper member sorting lifter 1 is set to a predetermined size on the basis of the instruction information input in advance. The member a travels to the sorting position where heaps are stacked and stops at that position.

After the stop, when the piston 4q of the fluid pressure cylinder 4p of the traveling lifter 4 starts to contract, the pair of X-shaped legs 4d of the traveling lifter 4 have an intersecting inclination angle about the intersecting pin 4i. The inclination is downward, and the support base 4b provided on the upper part of the leg 4d descends.

As the support base 4b is lowered, the suspension beams 5 supported by the left and right support bases 4b are also lowered. Electromagnets 6 are suspended below the suspension beam 5 at predetermined intervals. When the support base 4b of the traveling lifter 4 descends, the electromagnets 6 descending together with the suspension beam 5 move to the mount 2 It descends on the member a piled up at a predetermined position of and is adsorbed on the upper surface thereof.

At this time, the electromagnet 6 is energized while the hanging beam 5 is descending, and the function of the magnet is exerted. Therefore, the electromagnet 6 descends to the upper surface of the member a made of a magnetic material such as a model rope. When landing on the member a, the member a made of a magnetic material is absorbed by the function of the magnet. Since the member a is made of a magnetic material, it is attracted by the electromagnet 6.

In this case, whether or not the electromagnet 6 provided below the suspension beam 5 has landed on the member a is confirmed by the landing confirmation limit switch 7. That is, when the electromagnet 6 lands on the member a, the vertical moving platen 5d stops its descending at that position, but there is a gap between it and the vertical moving platen 5d, and the vertical moving platen 5d stops descending. However, the fixed plate 5c and the suspension beam 5 are further lowered.

Then, the landing confirmation limit switch 7 provided on the lower portion of the fixed platen 5c comes into contact with the surface of the vertical moving platen 5d, and the landing confirmation limit switch 7 is turned “ON”, whereby the electromagnet 6 is turned on. Is confirmed to have already landed on the member a.

When the landing confirmation limit switch 7 confirms the landing of the suspension beam 5, the descent of the traveling lifter 4 is stopped. When landing is confirmed by the landing confirmation limit switch 7, the piston 4q of the fluid pressure cylinder 4p is changed from the contracted state to the extended state, and the pair of X-shaped legs 4d whose crossing inclination angle is inclined downward are It begins to tilt upwards. As a result, the support base 4b provided on the upper portion of the leg 4d starts to move up.

When the support base 4b rises, the suspension beams 5 whose both longitudinal ends are supported by the support base 4b also start to rise together. When the suspension beam 5 rises, the electromagnet 6 provided below the suspension beam 5 is also pulled upward by the suspension beam 5. The member a is attracted to the electromagnet 6 that is pulled upward, and the member a is also pulled up together.

In this case, whether or not the member a is adsorbed on the electromagnet 6 is confirmed by the member adsorption confirmation sensor 8 provided on the vertical moving plate 5d. If it is confirmed by the member adsorption confirmation sensor 8 that the member a is not attached to the electromagnet 6, the piston 4q of the fluid pressure cylinder 4p of the traveling lifter 4 is changed from the extension operation to the contraction operation again. The traveling type lifter 4 descends. Then, the same operation as described above, that is, the hanging beam 5 descends and the electromagnet 6 lands on the member a, is repeated.

When it is confirmed by the member adsorption confirmation sensor 8 that the member a is attracted to each electromagnet 6, the suspension beam 5 for pulling up the member a by the electromagnet 6 is raised. Then, when the suspension beam 5 rises to a certain height, the lifting operation is stopped, and subsequently, the motor 4h of the traveling lifter 4 is driven to rotate the wheels 4g of the traveling platform 4c so that the traveling lifter 4 moves. The rail 4a travels, and the hanging beam 5 is moved on the conveyor line 3.

The member a is attracted to the electromagnet 6 below the moving suspension beam 5, and the member a is carried from the gantry 2 onto the conveyor line 3. When the suspension beam 5 moves to above the conveyor line 3, the motor 4h of the traveling lifter 4 stops, and the suspension beam 5 stops traveling on the conveyor line 3.

After that, the piston 4q of the fluid pressure cylinder 4p of the traveling type lifter 4 starts to contract, and the pair of X-shaped legs 4d whose crossing inclination angle is inclined upward starts to incline downward, and the upper part of the leg 4d. The support base 4b provided at the bottom starts to descend. As a result, the suspension beam 5 whose both ends are supported by the support bases 4b of the left and right traveling type lifters 4 also descends, and similarly, the electromagnet 6 provided below the suspension beam 5 and the member a attracted to the electromagnet 6 are also adsorbed. Also descends downward.

When the member a to which the electromagnet 6 is attracted lands on the conveyor line 3, the landing confirmation limit switch 7 provided downward at the bottom of the fixed platen 5c comes into contact with the lower vertical moving platen 5d. By doing so, the landing confirmation limit switch 7 becomes "ON", and it is confirmed that the member a has landed on the conveyor line 3.

When the landing confirmation limit switch 7 confirms that the member a has landed on the conveyor line 3, the electricity flowing through the electromagnet 6 is cut off, and the member a attracted to the electromagnet 6 is cut off. Is released from its adsorption.

After that, the piston 4q of the fluid pressure cylinder 4p of the traveling lifter 4 is extended again, so that the pair of X-shaped legs 4d whose crossing inclination angle is inclined downward are inclined upward, which causes the support base 4b. Rises, and the suspension beam 5 and the electromagnet 6 supported by the ascending support 4b also rise.

The member-on-frame sorting lifter 1 conveyed by the member a on the conveyor line 3 moves from the position on the conveyor line 3 to the frame 2 and returns, and thereafter the member a on the frame 2 is moved to the conveyor line 3 by the same operation. It will be moved up and transported.

The same operation is performed also when the member a on the conveyor line 3 is conveyed to the gantry 2.

During the carrying operation, the electromagnet 6, the suspension beam 5, etc. sway with respect to the suspension beam 5 when moving between the gantry 2 and the conveyor line 3 or when moving up and down. Therefore, it is possible to surely lower the member a that is attracted and suspended by the electromagnet 6 to a predetermined position, and accurately lower the electromagnet 6 onto the member a that is placed at the predetermined position. Therefore, the member a placed at a predetermined position can be reliably pulled up and conveyed.

The present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[Effect of device]

 As is clear from the above description, according to the on-member sorting lifter according to the invention of claim 1, the longitudinal beams of the suspension beam for suspending the members via the electromagnet are located above the traveling lifter. Since it is placed and supported, unlike the conventional case where it is supported by being suspended by a wire rope, it stabilizes without shaking, so that the suspension beam that attracts the member via the electromagnet can be accurately positioned at a predetermined location. It can be lifted up and down or can be lifted up accurately from a predetermined location, which facilitates the positioning of the ups and downs of the members and, as a result, facilitates automation. In addition to this, the lifter is cheaper than the crane method, and the equipment cost of the entire device can be significantly reduced. For example, it can be halved as compared with the crane system.

In the case of the structure according to claim 2, when the left and right traveling type lifters supporting the longitudinal end portions of the suspension beam are not at the same height when moving up and down, the longitudinal end portions of the suspension beam become the traveling type lifter. On the other hand, since it is hinge-supported and freely rotatable, it is possible to prevent an unexpected force such as a bending moment from acting on both ends of the suspension beam in the longitudinal direction and the supporting portion of the traveling lifter.

In the case of the third aspect, it is possible to absorb the impact when the electromagnet lands on the member and prevent both the electromagnet and the member from being damaged by the impact when landing.

In the case of the configuration of claim 4, it is possible to confirm that the electromagnet lands on the member, and it is possible to prevent the electromagnet from lowering more than necessary and damaging both the electromagnet and the member.
